Application filed September 28, 1925. Serial No. 59,014.

This invention has for its object to provide window fixtures such aswindow-shade roller brackets,y curtain rod brackets and other devicesusedy in conjunction with draperies and window-shades, which are .easilyand quickly attachable to metal window frames without requiring the useof toggle vor expansion bolts, 'or the tapping of perforations in thewindow frame for the reception and engagement ofthe shanks of machinescrews for'securing such fixtures or devices, and further, tol providemeans whereby the said fixtures or devices are permanently rigidlysecured in place.

A further object of the'invention is to provide fastening devices forsecuring such devices or fixtures to metal window frames and the likewithout necessitatingthe tapping of perforations,to thereby permitfixtures adapted for mounting on wood window-casings and the like to bealso mounted on metal frames or casings. i

Heretofore, fixtures have been secured to metal window and door-casingsby either boring and tapping yperforations in the latter to receivev andrengage machine-screws pass,- ing -through perforations in the fixtures,or by boring perforations in the casing and insei-ting toggle-bolts orexpansion bolts. The first-mentioned method is both slow andineflicient. because of the thinness of the metal of which the casing iscomposed, and the second method is also slow and more expensiveandproduces a clumsy-looking effect.

My invention comprehends the provision of means integral with thefixture or em bodied ina separate device which isboth cheap and veryneat inappearance, a characteristic common to both embodiments beingthat the attachment of the fixture is very quickly and easily effectedand is-both rigid and permanent. i

All such fixtures include base or wall-plates, the latter beingindicated at Figs. 1 t0 6 inclusive; by reference numeralQ in Figs. 7

'to 9'4 inclusive, by lreference numeral 3 rin Figs. lO'to 12 inclusive,and by reference numeral 4 inFigs. 13 tof15 inclusive. K

The invention furthereomprelends j a certain degree of" flexibility or elasticity in thefastening. device which materially, aids in so attachingr the fixtureas' to al'ways cause the base or Wall-plate thereottobear soV firmlyupon the casing; as to preventA all relative Inoveinentdbetween thelatter andthe tiktureunder the` severest strains or stresses to Wliichthe'li'xtures are usually subjected.

The projections are impairs. extending` from oppositeedges` of. the plate and diametricallyj of the same. Y

Tll'ey are relatively so positionedthat. the distance between't-ll'eir centers is greater than tle'distanceseparatingthe free endportions ofi tle projections and so` that whentile latter are passed "through the said perforations their opposingfaces will' contact with they Walls of the respective perforations-leastremoved ,from cach other.

TheplatelG-sliownin Figs. l() to 12inclusive is adaptedffrisecuring theconventional" Window-'shade rollerbracket' of Figs. 10 and 11, the baseor wall-plate 3 of which comprises a flange of the bracket element andis provided with two perforations in which the conical projectionsformed by the indentations 18 engage. The plate 16 is longer than theplate 3 and upon clinching its end projections 19 will be slightlyflexed, for purposes aforesaid.

In Figs. 13 and 14, I have illustrated the conventional type ofwindow-shade roller adapted to be mounted on opposed side faces of thewindow casing and which includes the plate 4 provided with perforationsfor the passage of fastening devices and the central dished portion 2Owhich is slotted or perforated to receive an end element of ashade-roller, this dished portion being circular. The plate 21 providedwith clinchable projections 22 and indentations 23 to engage in theperforations of the plate 4, is provided with a central, circularopening 25 through which the dished portion 2O is adapted to project,the plate 21 being somewhat longer than the plate 4, so that uponclinching the projections 22 it will be slightly flexed as and for' thepurposes aforesaid. v

From the foregoing it will be obvious that any kind of a .fixture may beeasily and rigidly secured toa metal` casing or trim by means of a platedesigned to adapt it for co-operat-ion with the perforations of thefixture ordinarily used for the passage of fastening devices or byproviding the wallplate or plates of the fixture' with the integralclinchable projections shown in Figs. 1 to 6 inclusive. l

In so far as the tool above described constitutes a part of theinvention, the latter may be expressed as constituting a method asdefined in appended claims.
